Extracts reusable UI component patterns (buttons, cards, forms, inputs) from a screen with their styles and variants.
AI agents call extract_components to retrieve information from Stitch MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only analysis of design data. It identifies and retrieves component information from existing screens for cataloging purposes. There are no side effects, no code execution, no data modification, and no irreversible actions. The operation is purely informational extraction, placing it squarely in the Read category with low severity.
From the tool's definition Tool 'extracts' UI component patterns 'from a screen' — it queries and retrieves component definitions without modifying or executing any code.
Attacks that exploit this kind of access
Extracts reusable UI component patterns (buttons, cards, forms, inputs) from a screen with their styles and variants. It is categorised as a Read tool in the Stitch MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Stitch MCP Server MCP server in PolicyLayer and add a rule for extract_components: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Stitch MCP Server. Nothing to install.
extract_components is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the extract_components rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for extract_components. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
extract_components is provided by the Stitch MCP Server MCP server (oogleyskr/stitch-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
